kami turunkan hujan atas mereka dengan lebatnya, dan kami jadikan sungai-sungai mengalir di bawah (SURAH AL-AN'AM,6)

Hujan --- higher level (sky) --- provide water for below level

Sungai --- lower level (earth) --- receive the water for human and other livings need.

Two different creation of Allah that build a CONNECTION that provide needs

for human, animals and environment.
